Visual Impact Assessment capability development - phase 3

Warning

The viewshed maps on this page are very detailed and may take quite a while to display in many web browsers, and may not render at all on small devices such as smartphones or tablets. They are provided purely for development purposes, and final versions will be optimised for faster display.

Calculating compound viewsheds

In this step, we will calculate the cumulative viewshed for all of the 47 turbines proposed for the Palings Yard wind farm, assuming each one is 240m tall. This assumptin will be varied in the next step.

We can examine the distribution of the number of turbines visible from each pixel in the cumulative viewshed raster. Note that zero turbines are visible from the vast majority of pixels – these have been excluded from the chart below.

The map below shows the cumulative viewshed (with Earth curvature and atmospheric refraction corrections) for all 47 of the proposed Palings Yard wind turbines each 240 metres tall at the indicated positions, shaded by the number of turbines visible from each point on the map.
